[Bug-apl] Cell grid in ⎕CR output?

[Elias Mårtenson]

Would it be possible to add a ⎕CR mode where matrices are displayed in a grid?

In other words, instead of displaying 3 3⍴⍳9 like this:

┌→────┐

↓1 2 3│

│4 5 6│

│7 8 9│

└─────┘

I'd like it to be displayed like this:

┌→┬─┬─┐

↓1│2│3│

├─┼─┼─┤

│4│5│6│

├─┼─┼─┤

│7│8│9│

└─┴─┴─┘

I was looking at the code, and it actually seems slightly harder to do than I expected since the frame around a matrix is drawn separately from the actual content, and the grid-style requires that the frame changes depending on the alignment of the actual cells inside the matrix.

However, I still would like to ask if there is a way to do it, as there are cases where the grid notation is much more clear.
